will I experience any bottlenecks on this system??
is it worth getting a 3770k if I am going to crossfire 7950's?
You could run 2 Titans on that without bottlenecking, 2x 7950's will be a Breez for it.
What Mobo/Cooler you running to get that OC and at what Voltage ?
I am running an asus p8z77-v lx and a corsair h100 with pull fans
current voltage I dunno......I think it's at 1.425 though......
